Olethreutini Olethreutini are a large tribe (over 1,200 described species) with a worldwide distribution. In a multi-gene molecular analysis by Regier et al. (2012), Bactrini and Endotheniini, formerly considered distinct tribes (Horak 1998), were found to be deeply embedded within Olethreutini and hence, those two tribes were synonymized with the latter. Most species of Olethreutini are leaf-rollers in dicotyledonous plants; about half are food-plant specialists and half polyphagous. In addition to leaf-rolling, there are a number of seed and fruit feeders and a few stem-borers. During the survey in Ecuador, a single representative of the tribe Olethreutini was reared from leaves.
